PLOW-CLEANING ATTACH M ENT.

SPECIFICATION forming part of Letters Patent No. 427,408, dated May 6, 1890.

Application filed February 8, 1890. Serial No. 339,686. (No model.)

T0 at whom, it may concern.-

Be it known that I, CHARLES VALENTINE DY ER, a citizen of the United States of America, residing at Oonroe, in the county of Montgomery and State of Texas, have invented certain new and useful Improvements in Plow- Cleaning Attachments; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will en- 1 ble others skilled in the art to which it appertains to make and use the same, reference bein had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

This invention relates to attachments for plows, designed to keep the mold-board clean; and it consists in the improvements hereinafter described and set forth, whereby the soil is automatically prevented from adhering to said mold-board.

In the accompanying drawings, forming part of this specification, Figure 1 is a perspective view of a plow embodying my improvements, and Fig. 2 is a section of the same on the dotted line a: w.

The beam A of the plow carries at its rear end the standard 13, the lower portion of which, together with a horizontal rearward extension, forms the landside of the plow. The beam carries on its upper side a box a, in which bears one end of a transverse roller 1), the outer journal of which is seated in the upper end of an inclined bar 0. A transverse brace d is seated at oneend in a recess therefor in the front of the standard, while the other end bears in the bar 0. A lower roller 6 bears in .the standard and lower end of said bar. A transverse brace f is also seated in the standard and outer bar.

The mold-board proper consists of three pieces g h 1', which are secured on the lower and upper braces d f, so as to leave longithe standard B. Two endless belts kl pass around the upper and lower rollers, and are connected transversely by blades or scrapers m, which have curved front edges and are attached to the straps in line with the slots between the sections of the mold-board.

The hanger E depends from the beam near its front .end, and has a colter-wheel m hung therein, the outer journal 0 of which projects for the attachment thereto of a pulley p, geared by a belt with a corresponding pulley g on the projecting end of the upper roller.

In operation the colter imparts a rotary motion to the upper roller to cause the scraperbelts to travel. Each scraper passes down closely over the mold-board, its connections with the belts moving along the slots. As the scrapermoves as stated its curved edge cuts and dislodges the earth adhering to the mold-board, and the said scraper finallypasses from the mold-board beneath the section D and turns with the belts around the lower roller and again comes into position at the top of the mold-board.

\Vhile I have represented three scrapers, as many may be employed as may be found desirable.

The device is particularly serviceable in plowing in the black viscous soil common to certain localities.

-A transverse plate S is pivotally connected to the upper edge of the front section, to provide for a limited movement when the scrapers pass beneath the same.

I claim 1. The combination, with the stationary mold-board of a plow, of lower and upper transverse rollers, belt-s passing around the same, carrying scrapers adapted to pass over said mold-boards, and means for operating said belts, substantially as set forth.

2. The combination, with the mold-board of a plow, having parallel longitudinal slots, as described, of upper and lower rollers, belts passing around the same beneath the moldboard, scrapers connected to said belts in llne with the slots and adapted to pass over said mold-board, and means for rotating said belts, substantially as set forth. 7

3. The combination, with the mold-board of a plow, longitudinally slotted, as described,

rying scrapers, of a rolling eolter having a pulley geared to a similar pulley on one of said rollers to operate the belts and scrapers, substantially as set forth. e

In testimony whereof I affix my signature in presence of two witnesses.

CHARLES VALENTINE DYER.
